Can Your Cell Phone Kill You? New Study Aims to Find Out

As cellular telephone usage has become widespread, so have concerns over the possible risks to health. Now the biggest study of mobile-phone usage yet, launched at the Imperial College London, aims to find a conclusive answer to the question once and for all: Could our cell phones be killing us?

Cell phones emit radio waves, a form of non-ionizing radiation, and because some types of radiation can cause cancer, some people are concerned. But this kind of radiation doesn't damage DNA, according to the American Cancer Society.

An estimated $100 million or more has been spent so far around the world on research into possible health risks from using mobile phones, which since the 1990s have become an integral part of many people's lives. Most studies to date haven't found a link between cell-phone use and tumor development.

Evidence So Far

For example, a study initiated in 1994 at the National Cancer Institute and published in 2001 found no evidence of higher brain tumor risk among people who use cell phones compared with those who don't. But use of cell phones wasn't as widespread in the 1990s as it is today.

Not satisfied, mainly because of questions regarding long-term use and research design, this new study, called Cosmos, will run for 20 to 30 years and will follow the health of at least 250,000 participants aged 18 to 69 in five European countries.

"We will be looking at a range of different health outcomes, including other forms of cancers such as skin cancers and other brain disease such as neurodegenerative diseases," such as Parkinson's and Alzheimer's, Dr. Mireille Toledano, co-principal investigator of the study, told the BBC. She added that the study will look also at other neurological symptoms such as headaches, depression and sleeping disorders.

Some governments have attempted to legislate various constraints on cell-phone use. The French wanted to restrict mobile-phone advertising directed at children, and other campaigners urged governments to at least issue safety advice on the use of cell phones. Children, they generally say, shouldn't be given mobile phones until they're at least 12 years old. According to Pew Research, 75% of American teenagers have cell phones.

An estimated 270 million people in the U.S. currently own cell phones, and the estimates range between 4 billion and 6 billion people worldwide. Whatever the true number is, it's growing rapidly. Global spending on wireless equipment and services surpassed $1 trillion for the first time in 2009, according to technology research firm iSuppli.
